Does anyone have any ideas as to why Apple would not manufacture an mDP to HDMI adapter? They have their own brand of VGA and DVI adapters (I have used both), but every listing for a Mac says you you need to have a third-party adapter if you want to go to HDMI. Perhaps this is the conspiracy theorist in me talking, but it seems strange that they wouldn't make one for such a popular cable technology, even though I know they are trying to push Thunderbolt monitors. Do they have an idea of what makes these third-party adapters that they suggest buying die off prematurely, I wonder?

The image below is the video-out listing when I go to their online store.

So I was out of town over the holidays and my Dad's newer macbook pro was having the same issue. I was using an off brand DVI to HDMI as well as an Apple mini display to DVI. Since he has applecare, I sat on the phone with their support guys for an hour trying all kinds of display and graphic card resets, etc, to no avail. Then he asked me if I had a different minidisplay to DVI adapter I could try. I told him I shouldn't need to because the one I was currently using worked on a monitor I had and a Sony TV, but I tried it anyway. It was a cheap knockoff brand, but to my surprise, it worked!

He said he would replace my apple adapter when I got home. Anyway, long story long...this leads me to believe that all adapters are not created equal, and even the apple ones fail / only work in certain circumstances.
